Pathways and distances of fluid flow during low-grade metamorphism: evidence from pyrite deposits of the Cameros Basin, Spain

open access: yes, 1999
New geochemical and sulphur isotopic data are presented for a number of pyrite deposits from the Late Jurassic–Early Cretaceous Cameros Basin, Spain. The deposits were formed at, or close to, the peak of metamorphism and are always related to sandstone ...

The Earth's Greatest Porous Media

open access: yesPerspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.
Abstract How deeply does modern meteoric water circulate into the continental crust? How deep is the Earth's Critical Zone (CZ), the top layer of the continental lithosphere that co‐evolves with the atmosphere, hydrosphere, and biosphere, extending from vegetation canopy down to fresh bedrock and the base of active groundwater circulation?

Behavior and mortality of anurans on roads in the Australian tropics

open access: yesThe Journal of Wildlife Management, Volume 90, Issue 5, July 2026.
Roads are a major source of mortality for wildlife, particularly amphibians. Identifying vulnerable species and understanding any behavioral predictors of mortality helps us understand vulnerability to traffic and can inform management strategies. We investigated a 9‐species anuran community in tropical Australia with respect to 3 behavioral responses ...
